Final answer:
The provided information is incomplete and unclear to determine the measures of angles ABC and FEC.
Step-by-step explanation:
To find m∠ABC, we need to look for the angle value associated with that term in the given information. However, the provided information is not clear or complete enough to identify the specific angle. It is recommended to review the attached document carefully and check for any additional details or diagrams that may provide the required information.
To find m∠FEC, we also need to look for the angle value associated with that term. Again, the given information does not provide a clear measurement for this angle. Make sure to review the attached document and search for any relevant data or illustrations.
